White Sand, Dry Landscape

Quick answer：

Dry landscape, also known as 'karesansui' in Japanese, is a form of Japanese garden design that emphasizes the beauty of simplicity, using carefully raked white sand to represent water, rocks to represent mountains, and occasionally plants or moss to enhance the scene. It is a popular style for Zen gardens and reflects the principles of Wabi-sabi, which celebrates imperfection, asymmetry, and the transience of all things.
